MINDEN, Nev. (December 10, 2007) -- In conjunction with this
evening's Mazda North America Operations holiday party and 40th
Anniversary Celebration of the Rotary engine, Sierra Sierra Enterprises
announced that it has signed Jonathan Bomarito to contest the 2008 Cooper
Tires Presents The Champ Car Atlantic Championship Powered by Mazda.
Bomarito and team owners Dennis and Diane Kottke were present at the
Mazda celebration.

Bomarito brings a strong record of success to Sierra Sierra Enterprises
with 31 career Atlantic starts, two victories, one pole position and a
total of eight podium finishes. In 2007, Bomarito finished fifth in the
championship with a victory after starting from the pole position in San
Jose, and he is looking to be a front runner in the championship sprint
for 2008 first place title.

"When I received the call from Richard [Raeder, Sierra Sierra Team
Manager] I was thrilled," Bomarito said. "I'm so
excited to start working with the team and to test in the spring. This
was the best news I could have hoped for."

Bomarito joins American rookie Dane Cameron, the 2007 Star Mazda
Champion, on the two-car Sierra Sierra Enterprises team, which claimed
its first Atlantic championship in 2007 with driver Raphael Matos. Both
Bomarito and Cameron hail from California.

"We are really looking forward to hearing the National Anthem
playing from the podium -- hopefully after every race," said
Diane Kottke. "We are very proud to be in a position to work with
talented drives like Jonathan and Dane. We are very excited to get this
season started!"

"With a championship title to defend there is definitely more
pressure to perform," added Raeder. "Having a team with both
an experienced driver and a rookie is a great way to develop talent and
build on our success. We are really excited to have a driver of
Jonathan's ability on our team, and 2008 is shaping up to be a
great season."

With both drivers hailing from the Golden State, the season opener in
Long Beach is certain to bring the local crowd of supporters out in
force. The Toyota Grand Prix of Long Beach will take place on the
weekend of April 18 -- 20.
